Slamdance, launched 18 years ago as an alternative to Sundance, has already unveiled its competition lineup with 10 narrative films and eight documentaries — including 13 world premieres. Included in the fest that will take place Jan. 20-26 in Park City, Utah is the premiere of Best Friends Forever, which follows Harriet, a comic book artist with a secret, and her reckless BFF, Reba, who take their ’76 AMC Pacer on the open road and instead get a wild ride towards an impending nuclear apocalypse.

Starring Brea Grant and Vera Miao, the apocalyptic indie completed production after using their fans for money via Kickstarter. Grant, star of Rob Zombie’s Halloween II, directed the film.
